Select scientific modelling and chemical/biological limnology are part of our miscellaneous archives
The bathymetric map; the morphological data; the Papermill Lake watershed flow chart; peruse our predictive modelling, and view the relevant model; the watershed plan; the Nova Scotia lake hypolimnion project; the paleolimnology of lakes in the HRM
Our submission to the Regional Council dated June 12, 2006 delves into some detail
The Predictive TP/Cha base model along with control field data elucidates total correspondence even with latter data.
As the year-2004 CCME Policy on Phosphorus (TP) clearly narrates that not adhering to the reference/background (i.e., the natural pre-development value) + 50% maximum increase concept, even if they fall within the reference/background trigger ranges, could result in significant changes to the `COMMUNITY STRUCTURE' (cf. eutro1, and eutro2)
Our original recommendation of eight (8) µg/l (micrograms/litre) mean yearly TP for Kearney Lake was not based on the CCME's year–2004 policy since the recommedations were developed during the mid-1990s. While the CCME's policy was based on a 1991 paper published by NALMS (Hutchinson et al., 1991), nevertheless, it was not the official policy of CCME until year-2004.
A note of caution: There have been conflicting results in the long term removal of typical stressors in storm drainage using constructed (or engineered) wetlands. Further, such wetlands have not had a successful history in the amelioration of acid drainage in HRM. Hence, the only sustainable methodology would be treatment of urban and suburban stormwater by traditional wastewater treatment plants (WWTP) based on the tertiary removal process in the case of stressed lakes! This implies considerable capital costs and operation & maintenance.
